Flying Hangar Door
The 1983 “Flying Hangar Door” was home-designed and home-made by a very quiet and talented NASA engineer from Dryden Flight Research Center and weighed as much as a Vespa moped. The all-wing airframe was made of corrugated paper and the wheels were from child’s bicycles (plastic rims). It was powered by a lawnmower engine.
Despite its seemingly bulky shape, the “Flying Hangar Door” was an “excellent flyer”. It is possible that the aircraft never received a proper designation or even a registration.
